Coil Slitting Line

Precision Coil Slitting Lines Machine

Slitting machine also known as vertical slitting line is used to slit cold rolled steel coils, hot rolled steel coils, galvanized steel coils, silicon steel coils, stainless steel coils, aluminum coils etc. into different widths and slit as well as smaller metal strips are rewound at the end of the slitting machine according to the production requirements of the user.
These smaller strips are necessarily used in the manufacturing of transformers, motor manufacturing industry, pipe/tube welding plant industry, cold roll forming and other specialized areas of the next process use industry, ceiling plasterboard industry and other high precision equipment manufacturing and metal strip manufacturing industries.


  • Description Of Slitting Machine

    Slitting machine also known as vertical slitting line is used to slit cold rolled steel coils, hot rolled steel coils, galvanized steel coils, silicon steel coils, stainless steel coils, aluminum coils etc. into different widths and slit as well as smaller metal strips are rewound at the end of the slitting machine according to the production requirements of the user.
    These smaller strips are necessarily used in the manufacturing of transformers, motor manufacturing industry, pipe/tube welding plant industry, cold roll forming and other specialized areas of the next process use industry, ceiling plasterboard industry and other high precision equipment manufacturing and metal strip manufacturing industries. According to the material slitting thickness there are thin plate slitting machine, medium thick plate slitting machine and thick plate slitting machine.

    1. Roll and roll pad
    Use: Used for roll forming of steel pipes. Specific roll sets can be used to bend the steel strip into the desired diameter of steel pipe.
    Material: GCr15 or Cr12 or Cr12MoV
    2. Uncoiler and leveling machine
    Function: Uncoiler is a key component in the production line, mainly used to support and open the strip coil and feed the strip into the leveling machine.



    3. Shearing and Butt Welding Machine
    The shear and butt welder is used to cut the end of the strip just entering the live jacket and the head of the strip coming out of the uncoiler in parallel and then weld them together.
    4. Loop
    The live jacket is used to receive the strip from the uncoiler in a discontinuous manner while feeding the strip to the forming machine.
    It stores a certain amount of strip to ensure that the main machine can work continuously during loading and shear butt welding.

    Advantages:

    Cage bushing: low cost
    Spiral sleeve: protects the strip surface from scratches
    5. Solid state high frequency welding machine
    It is a computer-controlled high-performance heating device for welding steel pipes.
    Structure and working principle.
    The whole set of solid-state high-frequency welding machine consists of rectifier cabinet, inverter and output cabinet, connecting optical fiber, closed-loop water cooling system, central operating table, mechanical adjustment device, etc.
    6. Flying saw
    It is the automatic cut-to-length steel pipe equipment used in the continuous production of steel pipes
    7. Fine straightening machine
    Fine straightening machine is a kind of finishing equipment for high-frequency longitudinal welded pipe production line, which is used to straighten the steel pipe and eliminate the stress and bending of the steel pipe after forming and welding.
    8. Water pressure testing machine
    It is used to test the water pressure that the pipe can withstand. The equipment consists of main machine, auxiliary hydraulic system, centralized lubrication system, electric control system, emulsion and water circulation system.
    9. Automatic Palletizing Machine
    It is a kind of packaging equipment specially designed for steel pipe industry, which can realize automatic stacking of pipes into hexagonal or square shape and then automatic bundling.
    10. Slitting Production Line
    Slitting production line is mainly used to cut various wide steel strips into certain widths and then rewind them to meet the requirements of welded pipe and cold rolled section steel production.

    FAQ:

    Q: Are you a manufacturer?
    A: Yes, we are a manufacturer. We have 2 factories and our own technical team, welcome to visit us.
    Q: What information do you need before you can make a proposal?
    A: Pipe diameter, thickness range, application, raw material steel grade, coil weight and degree of automation.
    Q: What should I do if I am just starting a new business?
    A: Contact us immediately. We offer free pre-sales service advisors, and we can also help you with raw material (steel coils) procurement, worker training, international market prices, etc.
    Q: How do you do quality assurance?
    A: We have a special team to do strict QA, which is one of our advantages.
        (1) Every gear box is tested with oil inside for 8 hours to make sure there is no leakage.
        (2) Every shaft is checked for center runout.
        (3) Every drum will be checked to make sure it is within tolerance, and critical parts will be checked for all dimensions.
